ShadowQuest
Why don't you start by rewatching in order of appearance Ironman, Ironman 2, The Incredible Hulk (the one with Ed Norton and Liv Tyler), Thor and Captain America: First Avenger. Go to the end of the credits for the brief epilogue scenes that tie each movie to the Avenger initiative. That's all you need to know in preparation for Joss' movie.

jettamesis Well, that'd be a great suggestion, if I had a way to watch them. I'm not going to buy all those movies, and I can't afford Netflix. (I highly doubt my mother would add those to their queue just so I can see them.)

I think there might still be a Family Video in town - I'll have to check. But, again, there's the affording things issue. Sigh.
